Mou-

, IMPROVEMENT IN HANGING CRANK-SHAFTS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.-

Be it known that I, J AMES M. BEUGLER, of Wil- -liamsport, in the county of Lycoming, and State of Pennsylvania, have made a new and valuable Improvement to supercede t-he necessity of building strong,r and heavy foundations to secure Grank-Shafts in a fixed position,'by allowing the crank end of the shaft to vibrate freely and accommodate itselfto any throw or side nu'n'enient caused -by rapid motion, heavy labor; 85e.; and I do declare that the following is a f'ull, clear, and exact descriptionthereof`, reference being had to the accompanying drawing forming-part of' this 'speciticatioir f l To enable others skilled in the art to perform with my invention, I will proceed to describe its construction and operation.

To use luy invention for placing the crank-shaft in position for use, y l

First, construct a fiame, A, suitable for theV purposes intended to be aceomplishedby the power used.

Second, hangr to it theii'ame B by bolts or ball-joints C; into the frame B place the boxes D; into the boxes D insert the crank-shaft E; on the end of' the crank-shaft E 4plate the pulleyl F, the center of which must be on line with bolts orball-joiuts C C; on the other end of the shaft place the crank-wheel and wristpiu, G G, ou which attach the pitinan H.

.lhe dotted line I between C C represent-s the centers of'joint G Gand pulley, F, on shaft E. The lcrankwhe l G must have suliici'ent counterbalance to equal the weight of the driven parts att-ached to the wristpin G, which, when properly done will throw all vibrations laterally on box l), which when allowed to lnoye or vibrate laterally, as herein described, will do away with all other foundations for crank-shafts, ex-

cept to support the machine and work.

Having described a swing frame with the box D rmly attached thereto, and the crank-shaft E placed therein to attain the object desired, I do not wish to be confined to that particular form of machinery, as

.the same may be attained by allowing the box Don the crank end of the shaft to slide in a slot prepared f'or it, or other devices, to allow the shaft to vibrate laterally.

What I claim, and desire to secure by Letters' Patl entishe application to crank-shafts of a swinging or sliding-box which will allow the crank-shalt to vibrate `freely of its own accord, as herein described.

`Witness my hand and seal in the matter of my ap` plication f'or Letters Patent ou improvement inhanging crank-shafts.
